microchip s pickit
Microchip’s PicKit
  • USB flash microcontroller programmer
  • Costs approx. $30 US
  • Can be programmed in C++ or Assembly
  • Comes with a free IDE - MPLAB® (complete with programming and debugging facilities)
  • Can get free sample chips (6 of each type) from Microchip every 2 months
pickit components
PicKit components
  • Comes with 2 microcontroller chips - the PIC12F675 and PIC16F684
  • Supports other 8 and 14-pin Flash PIC® microcontrollers
  • Board has 8 LEDs, a potentiometer, input jumpers, and a push-button switch
  • Additional components can be added to the board
  • Additional I/O facilities can be added via daughter boards such as the PICTail
using the pickit for ice 4mi
Using the PicKit for ICE 4MI
  • Mike Devoy has developed a set of activities (see resources slide for URL)
  • Can be used to cover assembly, computer architecture, debugging expectations
  • Teach assembly, microcontroller architecture, using a debugger and IDE, and using the PicKit to program a microcontroller
  • Build up to controlling a traffic light intersection (or many other applications)
assembly
Assembly
  • Low-level programming
  • Common misconceptions
    • More difficult
    • More efficient
  • Analogy - walking instructions
  • Instructions versus statements
  • Instructions consist of an opcode (specifies the operation) and 1+ operand (parameter)
